energy by making the mechanism using the energy more efficient (and thereby requiring less energy to operate). In order to increase the use of renewable energy in the United States we need to develop a unified consensus on what energy is going to be used for which application so as the cost of renewable energy will decrease by the simple effect of supply and demand due to mass production and competition. Additionally‚ there will need to be federally and state mandated controls on the implementation

2013 Alternative Assessment Proposal (i) Application of chemistry/ chemical phenomenon Transition glasses have photochromic lenses which give eyeglasses the ability to change their tint level and adjust to the light that is available. They were designed to protect the eyes from harmful ultraviolet (UV) radiation and can be considered sunblock for the eyes. These lenses are clear indoors and darken outdoors for greater comfort in the sun. The photochromic lenses contain millions of

Sex determination in plants Summary- Evolutionary transitions happened gradually from hermaphroditism to monoec in which multiple sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes

Determination of Sulfate by Gravimetry Jose Luis E. De Guzman University of Santo Tomas‚ Sampaloc‚ Manila The determination of the percentage of sulfate in a sample is done as an instrument of learning a quantitative method of analysis‚ i.e.‚ of the gravimetric analysis. This type of analysis‚ which makes use of the weight of the samples was used for the experiment and required the precipitation of our analyte‚ SO4-2‚ and its filtration as a BaSO4 precipitate so as for weighing it. The weight

Growing up in an urban community can offer many obstacles that can hinder a person’s growth and affect their world view. In other words‚ urban areas can greatly affect the things you like and don’t like. Two recreational activities that are almost universally disliked by people who come from urban environments are soccer and golf. The reasons why may vary‚ but the most common are that they are both “boring” and “slow” sports and more importantly‚ don’t have many African-American players who are
